To on whom) it concern.-

Be it known that We, EDGAR E. COMAN and HARLEY S. SEELEY, citizens of the United States, residing at Prattville, in the county of l lillsdale and State of Michigan, have invented a new and useful Oar-Ooupler, of which the following is a specification.

The invention relates to improvements in car-couplings.

The object of the present invention is to improve the construction of car-couplings and to provide a simple, inexpensive, and efficient one adapted to be readily set for automatic coupling, and capable of obviating the necessity of going between cars during the operation of coupling.

Afurther object of the invention is to provide an automatic car-coupler which, when necessary, may be readily connected with cars having the ordinary pin-and-link carcouplings.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a car-coupling constructed in accordanee with this invention, the hinged link being set for automatic coupling. Fig. 2 is a view, partly in section and partly in elevation, of two draw-heads coupled. Fig. 3 is a transverse central view. Fig. 4 is ahorizontal sectional view.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a draw-head having a linkopening and provided at its top with an extension 2, and having a coupling-pin perforation extending through it and also through the part 2 and receiving an elongated coupling-pin 3. The extension 2 projects vertically from the top of the draw-head, and it is recessed at the back to form a hook. The rear wall of the hook extension is inclined, and the recess intersects the coupling-pin perforation and exposes aportion of the coupling-pin at the back of the hook in order that a substantially U -shaped link 4: may bear directly against the coupling-pin.

The U -shaped link. 4 is hinged to the drawhead atopposite sidesthereof, and is adapted to engage the hook of a corresponding drawhead, and when engagement with the same it draws against the coupling-pin thereof, as above described, thereby relieving the hook of strain. The link is provided at opposite sides with eyes, through which passes a transverse pivot-pin 5, and the sides of the link, when the latter is in an elevated position, as illustrated in Fig. l of the accompanying drawings, extend below the pivot, and are engaged by lateral projections 6 of a tubular slide 7. The tubular slide, which is substantially elliptical in cross-section, is arranged in the link-opening of the draw-head, and has a limited reciprocation. It projects from the draw-head, when drawn outward, as illustrated in Fig. 1 of the accompanying drawings, and it is adapted to be engaged and moved inward by a draw-head when two cars come together for uncoupling, whereby the depending terminals 8 of the link will be swung rearward to throw the body portion of the link downward into engagement withthe hook of the draw-head. The tubular slide is recessed to clear the transverse pivot or pin 5, which is provided witha longitudinal slot to receive the coupling-pin; and the lateral projections 6 are preferably formed by a crosspiece. The sides of the draw-head are provided with longitudinal slots 9, through which project the terminals of the cross-piece.

Only one link is employed to couple two cars, and in the event of the breakage of one link, the other one can be used; and when. the link isnot in use it is swung downward beneath the draw-head. When the link is swung downward, its sides engage the lateral projections of the tubular slide and move the same rearward within the draw-head. The link is provided at opposite sides with'arms 10, forming handles, and it is adapted to be swung upward in position for automatic coupling, before two cars come together, to obviate the necessity of a train-hand standing between the cars during coupling.

It will be seen that the car-coupling is simple, inexpensive, strong, and durable, that it is positive and reliable in operation, and that it is capable of coupling automatically. It will also be apparent that it is adapted to couple with cars having draw-heads arranged at different elevations and provided with the ordinary pin'and-link draw-heads, and that it permits the play incident to the ordinary pin-and-link car-couplings to enable cars of a train to be successively started.

Changes in the form, proportion, and minor details of the construction maybe resorted to without departing from the principle or sacrificing any of the advantages of the invention.

What we claim is- In a car-coupling, the combination of a draw-head having a link-opening and provided with a coupling-pin perforation and having at its top a hook extension, through which the coupling-pin perforation passes, the back of the extension being recessed to form a hook and intersecting the couplingpin perforation to expose a portion of a coupling-pin, a tubular slide arranged within a link-opening of the draw-head and provided with lateral projections extendingthrongh slots in the sides of the draw-head, and a swinging link hinged to the draw-head at opposite sides thereof, and having its terminals extended beyond the pivotal point and arranged to engage the lateral projections, when the link is in an elevated position, said link being adapted to engage the said projections to move the tubular slide inward, when it is swung downward, substantially as described.

In testimony that We claim the foregoing as ourown we have hereto affixed our signatures in the presence of two witnesses.
